gear is not a magic pill or injection that immediately gets you big and ripped. by no means can you lack or should you lack at all during training, diet or rest. i honestly do not think that it is possible for a natural lifter to lift as intense as someone on juice. i also understand when you say people start it too young, imo most guys just want to get big quick and not put in as much effort to do it naturally and most of the time they will stop lifting a few years after. but, if someone is going to put their training towards a use like competing in bodybuilding rather than just looking good, it is almost necessary to start gear at a young age to make it anywhere in the bodybuilding world nowadays...
